Combined effects of curing conditions and cement bypass dust addition on the compressive strength of fly ash-based alkali-activated materials

Abstract This study aimed to ascertain the possibility of replacing fly ash in alkali-activated materials (AAMs) with residues obtained through the extraction of chlorine from cement bypass dust (CBPD ex ). The effects of different cement bypass dust contents (5, 10, 15 and 20%)...

Fuzzy Modeling as a Tool Supporting the Energy Policy of Selected Municipalities (Poland)

Energy planning should focus on actions to save energy and reduce consumption while also implementing renewable energy sources to support sustainable urban development. In addition to global regulations, individual countries also have documents that facilitate energy management a...

Methane Capture and Hydrogen Production from Coal Mine Methane: A Sustainable Path for Energy Transition

Methane emissions from coal mines pose significant environmental and operational challenges. Methane can be released from coal seams and surrounding rock layers as a result of mining operations. These emissions pose environmental risks and can lead to fire and explosion hazards....

Receiver function imaging reveals Pyrenean-style crustal wedging in the Western Carpathians

The Alpine−Tethys suture in the Western Carpathians records the collision between the northern European passive margin and the Adria-derived Alps−Carpathians−Pannonian (AlCaPa) tectonic unit. Previous tectonic models, largely based on indirect evidence, proposed complex configura...

A Data-Informed Physical Asset Management Model for Maintenance Strategy Selection Under Reliability, Risk, and Uncertainty: A Scenario-Based Approach

Ensuring high levels of reliability and availability of industrial assets requires effective integration of maintenance decision-making within asset management frameworks. However, most existing approaches treat asset criticality, reliability assessment, and predictive maintenanc...

Deep learning method for wear assessment and regeneration support in gear hobbing tools

Efficient monitoring and regeneration of cutting tools are essential for maintaining product quality and process continuity in modern manufacturing environments. Consistent and robust assessment of tool wear remains a practical challenge, particularly when evaluations rely heavil...

Diagenetic controls on reservoir quality and heterogeneity of eocene red-bed sandstones: a case study from the Shahejie Formation, southern Bohai Bay basin, China

The lower sub-member of the fourth member of the Eocene Shahejie Formation (LSm-ESF) in the southern Bohai Bay Basin hosts red-bed sandstones that are increasingly targeted as deep hydrocarbon reservoirs, yet the quantitative controls of diagenesis on their reservoir quality rema...

Season-long match external loads in starters vs. non-starters in Brazilian professional women’s soccer

This study aimed to compare match external loads between starters and non-starters in Brazilian professional women’s soccer. Methods: In this prospective cohort, seventy outfield players (60.93 ± 6.10 kg; 166.39 ± 6.17 cm) from three teams competing in Brazil’s top division (Séri...

Comparison of the Mechanical Properties of 3D-Printed Materials PET–G and rPET–G

The use of recycled polymers in additive manufacturing has emerged as a promising strategy for reducing the environmental impact of polymer processing. However, the influence of recycling on monotonic and fatigue properties of polymeric materials manufactured by fused deposition...
